The mandrel is disassembled or dissolved after the part is cured and also difficulty in winding reverse curvatures(concave) b)relatively rough exterior surface (c) Expensive raw materials and higher fabrication cost and susceptibility to moisture It should be pointed out that structural materials are generally far more efficient in an extensional rather than in a flexural mode, making the arch and shell preferable over the beam and plate [8]. In general the layers are wound on a rotating mandrel,as presented in Figures 5 and 6Fibre Reinforced Composite (FRC) Structures 1945 Table 2: Typical Properties of Filament Wound Pipes (Glass Fiber Reinforced).
